Same here, I need to create comfortable environment and not have pressure of time. Or when the working girl just tries too fast to make you come and chase you out. I always try to book an hour and most of the time enjoy the second time. What helps me is a slow build up, foreplay, gentle kissing. Chances of this happening are slim with working ladies. Also I realised my skin around the member is very sensitive. Once the sensitivity is reduced and muscles relaxed I can last longer.
